Abstract
The invention is a precipitation-strengthened copper alloy, including the following components in percentage by weight: 80 wt %-95 wt % of Cu, 0.05 wt %-4.0 wt % of Sn, 0.01 wt %-3.0 wt % of Ni, 0.01 wt %-1.0 wt % of Si, and the balance of Zn and unavoidable impurities. According to the invention, the comprehensive performance of the alloy is improved by solution strengthening and precipitation strengthening; while the strength of the matrix is improved, the electrical conductivity of the alloy is hardly affected, the bending workability meets the requirements, and the stress relaxation resistance comparable to that of tin phosphor bronze is achieved. The comprehensive performance of the alloy of the invention is superior to that of the tin phosphor bronze C51900. Furthermore, the alloy of the invention is low in raw material cost, has obvious advantages in welding and plating.
